Patented Sept. 22, 1936 UNITED STATES PATENT OFFICE COLLAPSIBLE FURNITURE Isaac Stern, New York, N. Y. Application October 12, 1933, Serial No. 693,221 1 Claim. (Cl. 155-149) My invention relates to collapsible furniture made of suitable sheet material and more particularly to collapsible chairs.

' In places of public assembly it is often desirable to have readily available small chairs which can be easily conveyed to and from the point of assembly, and which are light, cheap and collapsible.

I have discovered that I can make a collapsible chair of sheet material such as cardboard, paper box board, corrugated paper, ilber board or any other suitable material adapted to be stamped or bent on scored or creased lines.

Accordingly, the main object of myinvention is to provide a collapsible chair made oi sheet material.

A Vfurther object is to provide a light, easily conveyed, collapsible chair.

There are other objects which together with the foregoing wi1l.appear in the detailed description of the drawings which is to follow, in which: i

Figure 1 is a plan view of one unit used in one form of my invention.

Fig-ure 2 is a plan view of a section used in cooperation with the section used in Figure 1.

Figure 3 shows the assembly of Figures 1 and 2 collapsed for conveyance.

Figure 4 shows the two units of Figures l and 2 in assembled form and ready for use.

Figure 5 is a developed view of a modified form of my invention in which a substantially rectangular seat is formed.v

Figure .6 is a developed view of another modiilcation of my invention in which a triangular shaped seat is formed.

Figure '7 illustrates the assembly of devices shown in Figure 5.

Figure 8 illustrates assembly ofldevices shown '.10 in Figure 6.

Referring now more particularly to Figures 1 lto 4, my chair comprises a sheet of material Il provided with an elongated cut or slot I2 extending from the lower edge upwardly approximately .45 half way to a scored edge I3 extending across the sheet material. A second section I4 shown in Figure 2 is provided with a slot or cut I5 extending from the upward edge downwardly about half way as shown. 'Ihe sheet material is cut in a 50 substantially curved form as shown at I6 for the purpose to be described hereinafter. In assembly, the unit sheet I4 is slipped between the edges oi' the slot or cut I2, and the sheet I I is slipped along the slot I5 until the upper edge I8 of slot I2 and 55 lower edge i1 of slot I5 meet. as shown in Figures 3 and 4; Normally, when the unit is thus assembled, it may be collapsed, the surfaces of sections II and I4 lying in face to race relation as illustrated in Figure 4 and the upper portion I9 of sheet I I being turned on the scored edge I3. In this condition it is readily portable and can be carried by the ultimate user to any destination. At that point, the unit is easily assembled by 5 merely turning sheet I4 until it is in a plane at right angles to the plane of sheet II as shown in Figure 3. Section I9 is then turned on its scored edge I3 to form a horizontal seat as shown in Figure 4. By providing curved edge surface l0 I6 on the section 2| of sheet I4 protruding outwardly, there is substantially no interference with the garments of the person sitting on the seat and, in fact, this curved surface may be cut in any desirable shape to that en d as by making it conl5 cave, that is curved inwardly instead of convex as shown.

In the modification illustrated in Figure 5, I have provided sheet material 22 having transverse scores 23, 24, 25 and 26 permitting assembly 20 oi the unit into a rectangular structure as illustrated in Figure 7, with the section 21 of the blank turned on its scored edge 26 into a horizontal position las shown and providing a rigid and secure seat. In the collapsed condition a section of the blank is turned on the scoring into a compact, small, easily portable unit. In Figures 6 and 8, I have illustrated a rectangular shape seat in which blank 3l is provided with transverse scores 32, 33 and 34 on which a section of the 80 blank is turned as illustrated in Figure 8 to form a rectangular shaped member. Section 3B is turned on its scored edge to form a horizontal seat section.

I have found that sheet materials of various 35 types such as corrugated board have suflicient strength to carry the weight of the average individual and yet is light and compact and, as is obvious, can be easily constructed.

Although I have shown a few forms which my invention can take, it is obvious that it may take other forms and I may, if desired, use reinforcing members if necessary, and I do not intend to be limited except as set forth in the appended claim.

I claim:

A collapsible chair made of fibrous paper material comprising a plurality of blanks each slotted, the slots,` when the chair is in assembled position, extending from the top edge of one blank and from the bottom edge of the other blank i'or 50 permitting said blanks to be slipped into interlocking engagement, and a horizontal section extending from one blank and scored to move into horizontal position supported by a portion of another ot said blanks, the top corner of the 56 unsupporting portion of said supporting blank being cutaway.

ISAAC STERN.
